SPECIFICATION forming part of Letters Patent 3T0. 383,007, :7

Application filed February 4, 1888. Serial X0 it-3,020. (No uiotbl.)

To aZZ whom it may concern:

Be it known that 1, JOHN H. PATTERSON, a citizen of the United States,residing at Dayton, in the county of Montgomery and State of Ohio, haveinvented certain new and useful Improvements in Cash Registers andlndieators, of which the following is a full, clear, and exactdescription, reference being bad to the accompanying drawings, formingpart of this specification.

My invention has for its object an improve ment in the construction ofthis class of machines, and its novelty will be herein set forth, andspecifically pointed out in the claims.

In the accompanying drawings, Figure 1 is a sectional side elevation ofthe machine, showing a portion of the case likewise in section. Fig. 2is a plan view of the machine re moved from the case, looking in thedirection indicated by the arrow in Fig. 1. Fig. 8 is a plan view of thesupportingbar and its, sup ports and the drawer-bolt and gong-actuatingmechanisms. Figs. 4 and 5 are detail views of the supporting-bar. Figs.2, 3, 4, and 5 are drawn to the same scale, while Fig. 1 is drawn to adiminished scale.

The same letters of reference are used to indicate identical parts inall the figures.

The case A of the machine may be of the usual or anysuitableconstruction, and is provided with the usual drawercompartmentcontaining the till or drawer B, which in this instance is arranged,when unlocked, to be partially propelled from the case by the spring 0.

The machine within the case is supported by suitable side uprights, D,which are connected near their forward ends by a shaft, E, upon whichthe operating-keys F are strung and pivoted. As is usual in this classof ma chines, the forward ends of the keys project through a slottedplate in the front of the case and are provided with numbered buttonsrepresenting the values to be indicated and registered.

G H represent two banks of registeringwheels, of the usual oranysuitable construc tion, each wheelof the bank G being actuated by itscorresponding key through the medium of the dog I, pivoted to said keyand engaging with said wheel, as is customary, and well known in thisclass of machines, The rear ends of the keys extend back throughaslotted guide-plate, J, and carry vertical tablet-rods K, arranged inguides L and provided with the usual indicating tablets, M, arranged tobe exposed to view through the ordinary glRSSCOW ered reading openingsin the top of the cise.

N is a supporting-bar held and arranged to have lateral play in guidesin the side uprights of the machine. This bar is provided with verticalslots a, which receive the rear portions of the keys F. The walls on oneside of theslotsin this instance the right-hand sideare inclined orbeveled, as shown, said inclines terminating at their upper ends in offsets or shoulders b. Any suitable spring, 0, bearing against the end ofthe bar N serves to hold said bar in and return it to its normalposition of rest, with the righthand walls of the slots bearing againstthe sides of the keys, as seen in Figs. 2 and 4.

From this construction it will be seen that whenever the front end ofanykey is depressed, its rear end in rising bears against the inclined wallof its slot and pushes the bar F aside, until the key passes above theincline, whereupon the bar N returns toits normal position, with theshoulder Z) under the elevated key, in such manner that when the frontend of the key is released its rear end rests upon and is supported bysaid shoulder, as seen in Fig, 4, thereby holding up the tabletrod andthe tablet exposcd to view by the operation of that key. Upon operatinga second key, its rear end in rising bears against the inclined wall ofits slot and pushes aside the barN, thereby moving the shoulder b fromunder the previously-operated key and permitting it and its tablet-rodand tablet to drop, while the newlyoperated key is caught by theshoulder b of its slot and held with its tablet exposed to view, asbefore described.

It will be seen that two or more keys maybe operated simultaneously toregister their val vated tablet-rod and tablet preparatory to its secondoperation. In Fig. 3 is shown one form of such device, consisting of aspring pushbar, P, engaging with a horizontal incline on the lower frontside of the bar N. The neces sity for any such device is largelyobviated by the practice of employing duplicate keys and tablets of thevalues most frequently used, generally the keys from 5 to 25, inclusive,and commonly arranged at opposite sides of the machine.

The weight of the tablet-rods and the rear ends of the keys issufficient to reset them when released from their elevated position bythe movement ofthe bar N, though, if desired, the tablet rods may beprovined with the usual resetting-springs.

In order that the keys, when in their normal position of rest, may notrest directly against the bottoms of the slots in the bar N, and therebyinterfere with the free lateral movement of said bar, the bottom wall ofthe slotted guide-plate J is preferably arranged to hold the rearportions of the keys slightly above the bottoms of the slots in the barN, as seen in Fig. 4.

If desired, the upper portion of the bar N may be cut off level with theshoulders b, as that part of the walls between the slots which is abovethe shoulders I) is not essential to the operation of the machine.Again, while the bar N has been shown and described as being held in andreturned to its normal position by means of a spring, 0, the same resultmay be accomplished by dispensing with the spring and inclining theupper portions of the lefthand walls of the slots over the verticalportions of said slots.

The drawer-bolt and gong mechanisms are operated by the bar N in thefollowing manner: The drawer-bolt Q, of the usual or any suitableconstruction, is actuated by the lever B, pivoted, as at c, and havingits forward end engaging under a cam or beveled lug, (1, upon the lowerrear side of the bar N, as seen more particularly in Fig. 5, in suchmanner that when the bar N is pushed aside by the operation of any keythe lug (Z rides over and presses down the end of the bolt-lever R,therebylifting the bolt Q and unlocking the drawer, so that the drawermay either be opened by hand or automatically opened by the spring 0,where the latter is employed. The return of the bar N to its normalposition permits the bolt Q, to fall back to engage with the drawer whenthe latter is pushed in.

The gong S is suitably supported within the case, and is arranged to besounded whenever any key is operated, in the following manner: Atrip-lever, T, pivoted, as ate, is connected at its rear end by anysuitable means tothe bar Nin this instance by pivotal connection to lugsf upon the front side of said bar.

The arm T is provided with the usual shouldered tripping-dog, g, whichengages with the bell-crank h of the spring-pressed gong-ham- 'mer z.The movement of the bar N to the right upon the operation of any keycauses sufficient vibration of the arm T to throw back the gong-hammerz, the parts being so adjusted that just as the bar N reaches itsextreme limit of motion the dog y will have cleared the bell-crank h andthe gong-hammer will strike the gong. The return of the bar N to itsnormal position resets the arm T, and a light spring, j, causes thereengagement of the dog 9 with the bell-crank h, as will be readilyunderstood.

It will be noticed that whenever the bar N is moved aside by pushing inthe rod P the drawer is unlocked and the gong sounded, and the devicemay thus be utilized for the purpose of opening the drawer,when it isdesired to do so, without operating a key and actuating the registeringmechanism.

I am aware of the construction shown and described in Patent No.347,296, to Hopkins, and do not claim the same; but,

Having thus fully described my invention, I claim- 1. In a cash registerand indicator, the combination of the pivoted keys F, provided at theirfront ends with finger-buttons,and strung upon the shaft E, the verticaltablet-rods K, arranged in guides and carrying the indicatingtablets M,and the slotted supporting-bar N, operating when a key is depressed toits fullest extent toautomatically engage said key and hold its rear endelevated and its tablet exposed to view and to disengage said key andengage a second key when the latter is fully depressed, substantially asdescribed.

2. The combination of the keys F, pivoted on the shaft E, tablet-rods Kand tablets M, slot-ted supporting-bar N, drawer B, drawerbolt Q, and acam mechanism on the bar Nfor operating said bolt Q. substantially asand for the purpose described.

3. The combination of the keys F, pivoted on the shaft E, tablet-rods Kand tablets M, slotted supporting-bar N, gong S, and its gonghammer, andtripping mechanism between the bar N and said gong-ham mer operated bysaid bar, substantially as and for the purpose described.

4. The combination of the keys F, pivoted on the shaft E, tablet-rods Kand tablets M, slotted supportingbar N, drawer B, drawerbolt Q, gong Sand its gong-hammer, and connecting mechanism between the bar N and thedrawer-bolt and gong-hammer and operated by the bar N, substantially asand for the purpose described.
